What's Included: 1 x main Colour LCD alarm panel (433Mhz) 1 x wireless infrared detector (433Mhz) 1 x wireless magnetic door contact (433Mhz) 2 x Remotes controls (433Mhz) 1 x mini siren 1 x power adaptor (EU plug) 1 x user manual (English)  

Specification: Arduino 51 STM32 AVR MCU compatible Prototype expand The frequency is 850/900/1800/1900 MHz Power supply range: voltage is 5-12V; current is 1A or more (the current is very important). Operating temperature range: -40 °C to +85 °C Communication interface: The TTL level serial interface compatible 2.85/3.3/5V LED: Two led, the Net led and the RING led. Size: 48*50mm SIMCARD: micro SIMCARD holder Feature: TTL level serial port compatible with 3.3V and 5V microcontrollers. The initial use of computer debugging, it is recommended to use CP2102 USB-TTL module to power supply and communication; Using the MCU control module, you can also using the USB - 232 monitoring return data on the instructions, great convenience to find the problem, especially suitable for 51 MCU. Standby in 30MA or so, you can set the sleep state of about 10MA low power consumption. Support SMS, GPRS data transmission, send MMS, DTMF, HTTP, FTP, PPP dial-up and other functions. The hardware contains one channel reset pin. This reset pin can be used to resolve a problem with the module. Development board supports 2G / 3G / 4G Unicom or mobile phone card. Package includes: 1 x SIM800A Module Wireless Development Board 1 x Antenna Reference picture, test tools does not includes!

Instructions phone calls lights: Phone calls phone calls lights kit can be used to sense the GSM signal display, sensing distance up to 1 m, is a very interesting DIY module. Electrical characteristics: Supply voltage: 3 to 12V Sensing distance: about 1 m PCB board size: 2.2cm * 2.8cm Scope: GSM mobile phone signal, for CDMA phones are useless Note: This is a DIY kit, you need to assemble it. The circuit theory: The main circuit is amplified antenna sensor signal circuit and circuit. Sensing signal through the antenna 3 to S8050 transistor amplifier to drive the LED, so that light up. When no signal is detected, no calls or no GSM phones, LED circuit is not only detects the signal to light up LED. Inductance of production: Inductance 0.25 to 0.5MM enameled available in pen core above can be around 5-10 laps. After a good round with a blade to scrape paint inductor 2, so we go soldered to the board. Package includes: 5 x DIY Kit
